Essential Questions:
What are the units for measuring length in the customary system? How do we know which unit to use?
![Page 3: Customary Linear Measurement G5.4M.C4.PO3. I can choose the appropriate unit of measurement for any problem.](https://reader036.fdocuments.net/reader036/viewer/2022062517/56649ee85503460f94bf9596/html5/thumbnails/3.jpg)
There are 2 different systems of
measurement:
customary and metric
![Page 4: Customary Linear Measurement G5.4M.C4.PO3. I can choose the appropriate unit of measurement for any problem.](https://reader036.fdocuments.net/reader036/viewer/2022062517/56649ee85503460f94bf9596/html5/thumbnails/4.jpg)
The customary system is
primarily used in the United
States
The metric system is used in most of the rest
of the world

Today I can choose the appropriate unit for measuring
length and distances within the customary system.

There are four units for measuring length in the customary system:
Inches Feet Yards Miles
![Page 7: Customary Linear Measurement G5.4M.C4.PO3. I can choose the appropriate unit of measurement for any problem.](https://reader036.fdocuments.net/reader036/viewer/2022062517/56649ee85503460f94bf9596/html5/thumbnails/7.jpg)
Inches are the smallest unit in the customary system. One
inch is about the width of your thumb.
Inches are measured with
a ruler

Here are some objects that would be
appropriate to measure in inches:
length of a pencil height of a small flower
length of a paper clip

When you hold your arms out at both sides and measure from fingertip to fingertip, that is about the same as one yard.
There are 3 feet in one yard
There are 36 inches in one yard

A mile is the largest unit for length in the
customary system. Miles are used for very long
distances.There are
1,760 yards in a mile
There are 5,280 feet in a mile
![Page 14: Customary Linear Measurement G5.4M.C4.PO3. I can choose the appropriate unit of measurement for any problem.](https://reader036.fdocuments.net/reader036/viewer/2022062517/56649ee85503460f94bf9596/html5/thumbnails/14.jpg)
Here are some distances that would be
appropriate to measure in miles:
distance from your house to the mall
distance from Tucson, AZ to Disneyland
distance from Desert Willow to the U of A
![Page 15: Customary Linear Measurement G5.4M.C4.PO3. I can choose the appropriate unit of measurement for any problem.](https://reader036.fdocuments.net/reader036/viewer/2022062517/56649ee85503460f94bf9596/html5/thumbnails/15.jpg)

Your Turn!
What is the appropriate unit to use to measure each object or distance?
![Page 17: Customary Linear Measurement G5.4M.C4.PO3. I can choose the appropriate unit of measurement for any problem.](https://reader036.fdocuments.net/reader036/viewer/2022062517/56649ee85503460f94bf9596/html5/thumbnails/17.jpg)
Closure:
On your slate, write one example of an object/distance
you can measure with each customary unit of length. Be
prepared to share!
